Chapter 5. AppleTalk Basics


AppleTalk Addressing and Address Structure ” Fundamentals of the address and network structure of the AppleTalk protocol.

Configuring AppleTalk Addresses ” Overview of the AppleTalk addressing scheme, plus address configuration examples for different LAN and WAN interface types.

AppleTalk Routing Configuration ” Basics of AppleTalk routing configuration using static routes and verifying AppleTalk routing.

Configuring AppleTalk Routing Protocols ” Characteristics of the AppleTalk RTMP and EIGRP dynamic routing protocols, and basic configuration examples.

Configuring AppleTalk Filtering via Access Lists ” Controlling network access and security through the use of the access-list and appletalk access- group commands.

Configuring Basic AppleTalk Dialup Services ” Options for configuring the IOS to provide remote access to dialup AppleTalk users.

Verifying AppleTalk Connectivity and Troubleshooting ” Identifying connectivity problems through the use of the show , ping , and debug commands.

AppleTalk is one of the earliest implementations of client-server computing. It was created during the mid-1980s by Apple Computer for end users of the Macintosh product family to share resources, primarily printers and files located on servers.

While it gained a loyal following among its end users for its ease of use, AppleTalk simultaneously developed a somewhat negative reputation among network engineers and designers as a nonscalable protocol that was difficult to maintain in large corporate environments. While enhancements have eased some of the criticisms from the network community, the strongest advocates of AppleTalk remain its end users. Ironically, some of the features of AppleTalk that led designers to criticize it for excessive network utilization, such as dynamic address negotiation, have since been implemented on other widely deployed protocols, notably IP in the form of Dynamic Host Configuration Protocol (DHCP).

Figure 5-1 shows the various protocols within the AppleTalk suite of networking protocols. We do not cover all these protocols, but we instead focus on several at the network and transport layers ”namely, AppleTalk Address Resolution Protocol (AARP), Datagram Delivery Protocol (DDP), Routing Table Maintenance Protocol (RTMP), Name Binding Protocol (NBP), and AppleTalk Echo Protocol (AEP). Additionally, we explore Zone Information Protocol (ZIP) in the section "Configuring AppleTalk Filtering via Access Lists." The other networking protocols in Figure 5-1, which you might be familiar with, are provided as a frame of reference.

Not all revisions of the Cisco IOS support AppleTalk. You need to make sure that the IOS version that you are running on your router supports the Desktop Protocols Suite .
